Process for selective transfer of metallic foils to xerographic images

DETAILED DESCRIPTION A method is provided for forming imamges overlaid with metallic foil.
According to the method of the present invention, a sheet comprising xerographic images is provided and placed in face-to-face contact with a metal transfer sheet, to form a sandwich with the xerographic images on the inside.
Heat and pressure are applied to the sandwich, causing the xerographic images to become tacky and causing the metallic foil to selectively adhere to the images.
The remainder of the transfer sheet is then stripped away from the resulting decorated sheet comprising xerographic images overlaid with metallic foil.
In the preferred embodiment of the invention, the metal transfer sheet is provided with an adhesive of high filler content resin which has been found to produce good quality transfers to xerographic images produced by a wide variety of toners and photocopy machinery.
An important object of the invention is to provide a quick and easy method of selectively coating the image portions of a substrate with metallic foil.
This object is accomplished in accordance with the present invention, as for example in the presently preferred embodiment, by passing the sandwich through heated rollers at a suitable temperature and pressure for transferring the foil to the xerographic images.
Further objects and attendant advantages will best be understood by a study of the appended detailed description of the preferred embodiments, taken together with the drawings.
